Abstract

We present the first results from a study of O VI absorption around galaxies at z < 1.44 using data from a near-infrared grism spectroscopic Hubble Space Telescope Large Programme, the Quasar Sightline and Galaxy Evolution (QSAGE) survey. QSAGE is the first grism galaxy survey to focus on the circumgalactic medium at z ∼ 1, providing a blind survey of the galaxy population. The galaxy sample is H α flux limited (f(H α) > 2 × 10−17 erg s−1 cm−2) at 0.68 1014 cm−2) O VI absorption systems to be associated with M ∼ 109.5–10 M mass galaxies (Mhalo ∼ 1011.5–12 M dark matter haloes), and infer that they may be tracing predominantly collisionally ionized gas within the haloes of such galaxies.
